Value going straight from one person to another with no intermediary holding it along the way, at any hour, across any border.
Sending through a payment app, except no institution is warehousing the money overnight in between.
The promise that one token equals one dollar, and the machinery that keeps it there. A peg holds because the issuer will always redeem a token for a real dollar, so any gap gets arbitraged away within minutes.
A currency board, like the Hong Kong dollar's link to the US dollar, where a reserve pledge rather than market sentiment sets the rate.
A fake site, message or support agent designed to get your seed phrase, password or approval. In crypto it is the leading cause of loss by a distance, well ahead of any technical exploit.
Identical, and just as old. The difference is that a crypto payment cannot be reversed once it goes.
The plastic. Still the only thing that works at some terminals, and the only thing you can hand over at a restaurant counter.
The card in your wallet. Unchanged for fifty years, and still stubbornly necessary.
Brazil's instant payment system, free for individuals and available around the clock. It went from launch to near-universal in a few years.
An instant payment scheme run by the central bank itself rather than by the banks.
The secret number that proves a wallet is yours and signs every transaction. Anyone who has it owns the money. It is never typed into a website, ever.
Not your PIN. The actual key to the safety deposit box, where a copy is as good as the original.
Thailand's national instant transfer and QR standard, linked to a phone number or ID number and accepted almost everywhere, including markets and taxis.
A domestic instant payment scheme with a single national QR standard on top.
The rules a system runs on, usually as published code. In crypto the protocol is the institution, which is why people say 'the protocol decides'.
Card scheme rules. Visa's rulebook governs a payment far more directly than your bank's opinion does.
The shareable half of the pair, which your wallet address is derived from. Safe to post anywhere. It lets people send to you and lets anyone verify your signatures.
Your account number and sort code. You give it out precisely so people can pay you.
The Philippines' national QR standard, which made one code work across banks and e-wallets instead of a different sticker for each provider.
An interoperability mandate. One code, every provider, by regulation.
Indonesia's single national QR standard. One code on the counter that every Indonesian payment app can read, which is why the stickers stopped multiplying.
Money sent home to family across a border. The traditional route loses value twice, once to the transfer fee and again to a quietly unfavourable exchange rate.
The same word, the same money, the same families. Only the rails change.
In Kite: Someone sends you USDC or USDT and it lands as spendable dollars in your wallet, ready to tap on your card.
The real world assets an issuer holds so every token can be redeemed for a dollar. Reputable issuers publish what those assets are and have an accounting firm confirm it, usually monthly.
The capital and liquidity a bank has to hold against deposits, and the audit that proves it.
The dominant Layer 2 design. Thousands of transactions are compressed into one entry on the base chain, so each user pays a fraction of the settlement cost.
A processor batching a day of card transactions and settling them to the network once.
The internet address an app uses to talk to a blockchain. When a wallet says the network is unavailable, this is usually what it means.
An API gateway into a bank's core or a card network's switch.
The people behind a project drain the funds and vanish. Almost always a brand new token with anonymous founders and a return that could not possibly be real.
An exit scam, or a Ponzi collapse. The vehicle is new, the con is not.
Checking counterparties and wallet addresses against government lists before letting value move. Stablecoin issuers can and do freeze listed addresses.
Screening against OFAC and equivalent lists, which every bank does on every payment.
Paying a local merchant by scanning their existing QR code, in their currency, from a stablecoin balance. The merchant receives their own local money and does not need to know anything about crypto.
Using a foreign wallet at a domestic QR terminal, which is exactly the thing travellers normally cannot do, because those national schemes link to each other rather than to visitors.
In Kite: This is ours. Scan, review the exact amount, slide to pay. It draws directly from your balance, so there is nothing to top up and nothing stranded when you fly home.
Twelve or twenty-four ordinary words that regenerate your entire wallet on any device. Written down, it is the best backup there is. Photographed or typed into a support chat, it is the fastest way to lose everything.
A master key that reopens your vault at any branch in the world, combined with your password reset codes. No bank would ever ask you to read one aloud.
Anyone asking for your recovery words, for any reason. Support does not need them, wallet migrations do not need them, giveaways are not real. The request itself is the attack.
No bank has ever needed your full password read aloud. The rule transfers exactly.
You hold the keys, so no company can freeze, lend out or lose your money. The other side of that deal is that nobody can reverse your mistakes either.
Keeping your savings as banknotes in a home safe rather than in a bank. Total control, total responsibility, and no manager to call.
In Kite: Kite is non-custodial. Your keys are yours, and you can export them at any time.
The second half of a card payment, hours or days after authorisation, when the money actually moves and the held amount becomes a real debit.
The clearing and settlement cycle. The reason a pending charge changes slightly before it lands.
The currency an account actually keeps score in. Everything you spend in another currency gets converted back into it, and that conversion is where fees hide.
Your account's base currency. A dollar account that pays for a meal in baht converts at the card network's rate, plus whatever the bank adds.
In Kite: Ours is US dollars. Dollar spends carry no added fee and everything else is a flat 1.8%.
Cryptographic proof that the key holder approved something, without revealing the key. Every transaction you confirm is a signature. So is every wallet login.
A digital signature on a PKI certificate, or the chip in your card proving the card is present.
